 * Hello [@theworkshop](https://wordpress.org/support/users/theworkshop/) and thanks
   for reaching out to us!
 * Usually, when I see this message it’s due to the server being low on disk space.
   Since in a MySQLi setting, the WAF is stored in the database, so if the database
   is full, it won’t work properly.
 * Check with your host on how much space is available on your site and see if this
   is the issue.
 * Let me know what you find!
 * Thanks again!
